Diego Elio Pettenò	e7e2df27f8	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `d36beb3f69`)	14 years ago

Ronald S. Bultje	ac3c04e4d6	Don't do edge emulation unless the edge pixels will be used in MC. Do not emulate larger edges than we will actually use for this round of MC. Decoding goes from avg+SE 29.972+/-0.023sec to 29.856+/-0.023, i.e. 0.12sec or ~0.4% faster. (cherry picked from commit `44002d8323`)	14 years ago

Pascal Massimino	aa93c52c21	remove b4_stride/mb_stride. correct mb_xy to use mb_width. tighten allocations. reduce the amount of zeroing. Originally committed as revision 24760 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Pascal Massimino	ccf13f9e20	fix over-allocation. confused b4_stride with mb_width. Originally committed as revision 24758 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	6ce9b4310c	Remove use of the deprecated function avcodec_check_dimensions(), use av_check_image_size() instead. Originally committed as revision 24711 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	7e13022a4d	VP8: fix bug in prefetch Motion vectors in VP8 are qpel, not fullpel. Originally committed as revision 24707 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	905ef0d064	VP5/6/8: eliminate CABAC dependency Create a custom table for VP5/6/8's renorm to avoid depending on H.264's. Saves one instruction in the arithmetic decoder as well. Originally committed as revision 24701 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	1e73967950	VP8: partially inline decode_block_coeffs Avoids a function call in the case of empty DCT blocks (most of the time). Originally committed as revision 24691 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Jason Garrett-Glaser	370b622a45	VP8: eliminate a dereference in coefficient decoding Originally committed as revision 24671 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	f311208cf1	VP8: much faster DC transform handling A lot of the time the DC block is empty: don't do the WHT in this case. A lot of the rest of the time, there's only one coefficient: make a special DC-only transform for that case. When the block is empty, don't incorrectly mark luma DCT blocks as having DC coefficients. Originally committed as revision 24670 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	827d43bb9d	VP8: move zeroing of luma DC block into the WHT Lets us do the zeroing in asm instead of C. Also makes it consistent with the way the regular iDCT code does it. Originally committed as revision 24668 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Pascal Massimino	d2840fa49c	only store intra prediction modes on the boundary for keyframes, not as a plane. inter-frame behaviour unchanged. Originally committed as revision 24664 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
